Since January, 2020, Riku Mask China team and Japan team started to work on researching and studying antiviral material with application on facemask.

Many materials were given up during this process in half a year, including Silver ions and Copper ions which are considered to use on antiviral facemask by our competitors.

Finally we figured out the best antiviral material for facemask is nano materials that we are using now, it’s strongly supported by a lot of Lab test with live coronavirus which had been done in the past so many years. For careful consideration, we made physical samples with this material and submit to the third party Laboratory and test with Live corona virus including both Sars-CoV-2 (CoVid-19)  and Mers-CoV and found the result is satisfied and even excited .

Please check below test report for your reference.
Antiviral Test-Sars-CoV-2 (CoVid-19)
Antiviral Activity-Mers-CoV

Test result is telling that this is the right antiviral material which we need!
